Builder

✓ use builder_pattern::Builder;

Derives a builder for a struct and constructs an instance with chained methods.

use builder_pattern::Builder; #[derive(Builder)] struct Config { name: String, #[default = 42] value: i32, } let config = Config::new().name("test".into()).build().unwrap();

Debug

Known issues

gotchaThe macro requires all fields to have defaults or be explicitly set; missing fields cause a runtime panic.

fix

Use #[default] attributes or ensure all fields are provided before calling .build().

affects: >=0.4.0
